Among birds that can be attracted in the summer are brown thrashers, catbirds, robins, thrushes, waxwings, woodpeckers, orioles, cardinals, towhees and grosbeaks.

Although this is desert, there is an incredible diversity of bird life along the river and in other areas of the park - mourning doves, American kestrel falcons, nighthawks and brown thrashers are just a few of the birds that call it home.

The song can sound like hoots and whistles, in a repeating pattern similar to that of a mockingbird or thrasher.
